Definitions
- This invention pertains to torches and more particularly to a torch designed to provide a clean burning flame for the quartz and glass blowing industry. More specifically, the torch of the present invention is designed to provide a torch tip constructed entirely from ceramic that does not emit oxidized particles during operation.
- Torch prior art dictates that hydrogen and oxygen burn so rapidly that the gasses cannot be pre-mixed inside the torch. Rapid burning causes flash-back of the flame to the internal point of mixing. Separate and isolated hydrogen and oxygen emissions must be provided for external mixing to prevent flash-back.
- Prior art also provides that, to maintain a smooth and even burn, a multiplicity of very small gas emissions works much better than just a few large emissions for external mixing torches. These small emissions must be intimately adjacent to each other for proper mixing at exit. Most of the marketed oxy-hydrogen torches meet the foregoing prior art criteria. However, they are all made from metal and they all suffer similar disadvantages.
- At least one manufacturer of metal torches cautions that, reduced or normalized fires in the low flow range, will cause premature burn out of the tubes; and when used on a low soft flame, oxidizing effects should be maintained.
- the ceramic dual-gas externally mixing torch tip of the present invention is comprised of a multiplicity of intimately adjacent gas emission bores which are provided in a ceramic body.
- This ceramic body is sealed in a ceramic housing having two isolated gas chambers with respective gas supply ports for supplying separate gases under pressure respectively to these chambers.
- the ceramic body is housed within this ceramic housing such that the bores of the ceramic body exit to ambient for external mixing of gases issuing from the adjacent gas emission bores. Selected ones of these bores are connected exclusively to one of the gas chambers and selected others of the bores are connected exclusively to the other gas chamber within the housing.
- the ceramic body providing these intimately adjacent gas emission bores for external mixing of the gases consists of a multiplicity of clustered ceramic tubes with through bores and interstices formed between clustered tubes which provide these gas emission bores.
- Such ceramic tubing may be single bore ceramic tubing or is more preferably four-bore tubing which is commonly used for making thermocouples and is an off the shelf readily available item.
- the ceramic tubes are clustered together and interstices thus formed between the clustered tubes are all or selectively sealed off at the upper ends of the tubes to provide the remaining multiplicity of intimately adjacent gas emission bores which are exposed to ambient for external mixing of the gases.
- selected interstices between the upper ends of the clustered tubes, as well as selected tube bores are utilized as gas emission bores exposed to ambient. None, all or some of the interstices between tubes may be utilized as gas emission bores.
- Some of these clustered tubes may be shorter than others such that their bottom ends are exposed between the interstices of the clustered tubes to the one gas chamber and then the bores of the remaining longer tubes are exclusively exposed at their bottom ends to the other gas chamber within the ceramic housing.
- the interstices formed or created between the lower ends of the tubes are sealed off to isolate the respective gas chambers within the ceramic housing.
- Selected of the interstices between the upper ends of the tubes may be left open and used as gas emission bores along with the upper short tube bores.
- the sides of selected of these tubes are slotted or notched to thereby expose a predetermined number of these tube bores thereby providing upper and lower tube bore portions.
- the lower tube bore portions are then sealed or plugged off so that the notches and the upper tube portions are exposed exclusively to one of the gas chambers via the interstices created between the tube cluster and the path provided by adjacent slot arrangement.
- the exposed lower tube bore portions being plugged off totally isolates this one gas chamber from the other gas chamber within the torch tip housing.
- the multiple bore tubes are tubes of substantially equal length and the sides of these tubes may be slotted or notched thereby exposing only a predetermined number of the multiple bores within each tube, for example exposing only two of the four tube bores, thereby providing upper and lower tube bore portions.
- the lower tube bore portions are plugged in order to isolate the one gas chamber from the other gas chamber within the torch tip housing.
- the bottom ends of all the clustered tubes are also sealed therebetween in the interstices formed within the cluster to further insure isolation between the two gas chambers of the torch tip housing.
- the interstices formed between the upper ends of the tubes may be left open, selectively sealed off or all sealed off as desired.
- the positioning and orientation of these notches is preselected in order to provide a desired torch flame burn pattern, and to provide a gas path to the outer periphery of the bundle.
- a gas dispersion plate or element may also be provided in the other or bottom of the two isolated gas chambers for dispersing gas supplied thereto to provide homogeneous chamber pressure.
- FIG. 1 is the top view and burning end of the torch tip of the present invention. For clarity, only 18 of the 37 pieces of the tubular part 5 are shown.
- FIG. 2 is a cross-sectional view of FIG. 1 taken along line 2--2.
- FIG. 3 is an enlarged top view of a sub-assembly 7 of the torch tip shown in FIG. 1, which is assembled from 37 pieces of the tubular part 5 and base ring 6.
- FIG. 4 is a cross-sectional view of FIG. 3 taken along line 4--4.
- a preferred size, shape and burn pattern is depicted in the following description, but this does not preclude making other sizes, shapes and burn patterns using the same design principals. Hydrogen and oxygenate the two gasses mentioned, but other gasses may be substituted if applicable.
- the basic torch tip of the present invention is 2" diameter by 25/8" high. All parts are made from high strength non-porous ceramic. All parts are cylindrical or tubular in shape, and are easily formed by machine tooling.
- a slurry mixture of powdered ceramic and liquid hydrocarbons is made up to a consistency suitable to the application. Subsequent curing in a subsequent assembly will not effect a previously cured part. All ceramic used in the slurry mixture and individual parts is 99% pure alumina (AL 2 O 3 ).
- Hydrogen is supplied from the bottom of the torch and enters into an isolated hydrogen chamber. It then passes through 74 small emission holes to the top burning end of the torch.
- Oxygen is separately supplied from the bottom of the torch and enters into an isolated oxygen chamber. It then passes through its own 74 small emission holes to the top burning end of the torch. The supply of oxygen and hydrogen to the respective chambers may be reversed.
- Each hydrogen emission is intimately adjacent to a corresponding oxygen emission, and they mix immediately for ignition as they exit the torch. There is no contact of the two gasses inside the torch.
- the prime novelty of this invention is the method of construction, and more specifically, the practicability of constructing a torch of this nature from all ceramic parts.
- a unique element is the use of "four-bore tubing" commonly used for making thermocouples. It is catalogued and sold off the shelf in a variety of sizes. The specific size used here is cut from a standard 12" length, which is 3/16" diameter solid ceramic with four uniformly spaced 1/32" diameter parallel holes through its length.
- the novel use of this "four-bore tubing" eliminates impractical drilling of a multiplicity of deep and tiny parallel holes into hard ceramic, in close proximity of one another. However, single bore tubing may also be used.
- tubular part 5 and subassembly 7 are the key items for providing the multiplicity of separate and isolated gas emissions.
- one piece of tubular part 5 has been singled out and designated as part 5A for describing all thirty-seven pieces of part 5.
- Part 5A is made from a 7/8" length of 3/16" diameter "four-bore ceramic tubing".
- the two 1/32" diameter bores on the left penetrate all the way through, and are designated as hydrogen bores or passages 8.
- passage 8 connects the burning end of the torch with the isolated hydrogen chamber 9.
- Part 5A has a 1/4" high oxygen slot or notch 10 cut into its side, just deep enough to totally expose its two remaining 1/32" diameter bores on the right. They are designated as oxygen passages or bores 11.
- passages 11 connect the burning end of the torch with the isolated oxygen chamber 12, via the oxygen slot or notch 10.
- the two bores (lower tube bore portions) exposed at the bottom surface of the oxygen slot 10 are sealed off with ceramic filler 13.
- subassembly 7 is constructed by bundling thirty-seven pieces of ceramic tubular part 5 and adding the ceramic base ring 6.
- the oxygen notch 10 of each part 5 is shown in dashed outline in FIGS. 1 and 3, and each part 5 is rotated to position or orient the thirty-seven oxygen slots 10 as shown.
- this arrangement allows a preferred exposure to the oxygen supply producing a preferred burn pattern. Different burn patterns, satisfying other applications, may be provided by a different arrangement of oxygen slots 10.
- FIG. 3 and FIG. 4 show the triangular voids or interstices created when three pieces of part 5 abut each other. All, none or selected of these interstices at the top, and all of them at the bottom of the bundle are then filled to 1/4" depth with ceramic filler 14. Care is taken so that excess filler does not enter into and obstruct the oxygen notches 10. Also, the void spaces or interstices between the outer contour of the bundle and the inner peripheral surface of the base ring 6, are filled with ceramic filler 15 flush with the top and bottom of base ring 6.
- Subassembly 7 now is then oven cured, and all parts, adherents, and fillers, unite into one solid structure. After appropriate leak testing, we are ready for final assembly of the torch.
- the torch bottom or base 16 is machined from solid ceramic and shaped to receive all remaining parts.
- the hydrogen inlet hole 17, is counter-bored to receive the inlet tube 18 using ceramic adherent on all contacting surfaces.
- the oxygen inlet hole 19 is counter-bored to receive the inlet tube 20 using ceramic adherent on all contacting surfaces.
- the bottom surface of base 16 is chamfered to separate the inlet tubes for hose clamping room.
- the ceramic baffle plate 21 which is 1/8" thick and has six off center 1/8" diameter hydrogen dispersement bores 22, is seated onto its counter-bored ledge 23 in base 16 using ceramic adherent on all contacting surfaces.
- Subassembly 7 is seated onto its counter-bored ledge 24 in base 16 using ceramic adherent on all contacting surfaces. The void space immediately under subassembly 7, now creates the isolated hydrogen chamber 9.
- the outer ceramic cover 25 which has 1/8" thick side walls, is fitted over subassembly 7 and seated onto the outer grooved ledge 26 provided in base 16 using ceramic adherent on all contacting surfaces.
- the void spaces between the inner peripheral surface of cover 25 and the outer contour of subassembly 7, are filled with ceramic filler 27 flush with the top of the torch and 1/4" deep.
- the completed assembly then goes through a final oven curing process and emerges with all parts, adherents, and fillers united into a solid ceramic torch ready for use.
- the machined relief space 29 provided in base 16 allows it to flow into the isolated oxygen chamber 12. No baffling is required because limited in-rush and adequate dispersement is provided by the inner structure and overall peripheral expanse of the oxygen chamber 12. Oxygen now flows into each of the thirty-seven oxygen notches 10, and through each of the seventy-four bores 11 and interstices between the clustered tubes which remain unplugged or open in subassembly 7, to the top burning end 28 of the torch for externally mixing with the hydrogen.
- Each of the seventy-four hydrogen emissions is intimately adjacent to each of the seventy-four plus oxygen emissions as they merge externally for ignition. Again, the ease of fabricating this multiplicity of intimately adjacent emissions from ceramic, comes from the novel use of four-bore thermocouple ceramic tubing, which is a readily available off the shelf item.
- thermocouple tubing wherein two of its through holes access the isolated hydrogen chamber, and side slotting accesses the other two holes to the isolated oxygen chamber.
- the bundling of a multiplicity of side-slotted 4-bore tubings enables a multiplicity of isolated hydrogen accesses, and a multiplicity of intimately adjacent isolated oxygen accesses. Flame pattern is also controlled by preselected slot orientation.
- the preferred design embodiment described herein has a multiplicity of hydrogen and oxygen emissions with the possibility of more oxygen emissions through tube cluster interstices.
- the flame intensity and even burn capabilities may also be regulated.
- the two bores providing hydrogen and oxygen emissions need not necessarily be equal in number.
- the number of respective hydrogen and oxygen gas emission bores and arranging them to a desired configuration one may also regulate the flame burn pattern.
- selected of the single bore tubes may be cut short or be shorter in length than the longer single bore tubes which penetrate on downward into the hydrogen chamber 9. Accordingly the through bores in the shorter tubes are exposed exclusively to the oxygen chamber 12 of the torch housing via the interstices provided between the tube cluster of alternately adjacent longer single bore tubes.
- the number of interstices left open to ambient atmosphere between tubes, and the number of these short oxygen supply tubes and their specific location or orientation in cluster subassembly 7 may be regulated to provide the appropriate flame bum pattern and heat intensity.
- Burn pattern may also be altered by revising size, quantity and location of gas disbursement bores 22 in baffle plate 21.
